Unwanted hair distorts the complete look of people and also make them uncomfortable and less confident. Laser hair removal therapy has proven to be a boon for all such individuals. Laser hair reduction procedure involves permanently reducing hair from the unwanted part of the body and is completely safe and relatively painless.
Freedom from shaving and periodic waxing are just some of the benefits individuals seek through laser hair reduction.
There are two significant types of hair: terminal hairs and vellus hairs. Terminal hairs are thick, long, and usually pigmented with melanin. These include the hair on the scalp, underarms, genitals, and eyebrows. Hair from the chest, back, legs, and arms may also be terminal hairs. Vellus hairs or "peach fuzz" are short and non-pigmented and can be found in most other areas of the body and face. Lasers target terminal hairs with the pigment melanin.
There are three phases of hair growth: anagen, catagen, and telogen. Lasers can only target the anagen, or active, stage of the growth cycle. Anywhere from 20 to 85% of hair is in the anagen phase at any given time. This varies with different areas of the body. Regression begins in the catagen cycle. During the telogen stage, the follicle is "dormant" and prepares for the development of new hair. Because the laser can only treat hairs in the anagen phase, several treatments will be necessary for the desired result.
Lasers remove hair by the process of selective photothermolysis. The light energy from the laser is transferred as thermal energy in the hair follicle. When the thermal energy, or heat, is absorbed by the melanin in the cell structures (namely the bulge and papilla) they are destroyed. All lasers also come with a cooling mechanism that prevents damage to the surrounding cells.
Laser Hair Removal for Different Skin Types
Different skin types respond differently to the laser hair removal procedure. Henceforth it becomes quite necessary to have a proper consultation with the specialist before opting for this procedure.
Indeed each skin color responds differently to the concentration of laser beam as human skin have pigment cells that get activated while coming in contact with light. Fair or White Skin cells are less reactive to light, whereas darker skin types are more reactive. Best results occur in those with light skin and dark hair, and hair removal works better on coarse hair rather than fine hair.
Treatments will be Needed
Most procedures require 4-6 sessions for hair reduction of an area
